In a commentary in the May 9, 2007 issue of the Journal of the American Medical Association, scientists at the National Institutes of Health discuss why predicting the next pandemic is so difficult and outline steps that can be taken to better understand the behavior of the virus.
Drawing upon the lessons of past pandemics, the authors analyze the significance of the highly pathogenic avian influenza strain H5N1, which has spread among bird populations and infected hundreds of humans in the last decade. In preparing for the next influenza pandemic, however, the authors argue that researchers and public health officials should not focus solely on H5N1 strains, because the next pandemic might be caused by a different influenza virus.
Instead, research efforts should go beyond H5N1 and focus broadly on influenza viruses. This entails improving our knowledge of the basic biological and ecological means by which influenza A viruses infect birds; enhancing surveillance of infected animals and the circulation of influenza virus globally; understanding how the virus evolves and jumps from birds and other animals to humans; finding new approaches to vaccine design and vaccination; and developing new antivirals and diagnostics. Such broad activities can also help combat seasonal influenza, which is a major public health concern in the United States, accounting for an estimated 36,000 deaths and 200,000 hospitalizations each year.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
